To all whom it may concern.-

Be it known that I, OTTO KLATTE, a subject of the King of Prussia,German Emperor, residing at Neuwied-on-theRhine, Prussia, Germany, haveinvented certain new and useful Improvements in 'Rolls for Chain-RollingMills, of which the following is a specification.

My invention relates to a rolling mill of the kind described for chainbars in my application for patent filed March 8, 1892, Serial No.424,127, but "the invention is also applicable to rolling mills for themanufacture of smooth bars or bars with impressions of any kind.

Foreign patents have been granted for this invention as follows: inFrance, No. 232,132, dated August 11, 1893; in Belgium, No. 106,021,dated August 18, 1893; in Italy, No. LXVIII, 88, dated September30,1893; in Norway, No. 3,391, dated August 16, 1893; in Luxemburg, No.1,874, dated August 10, 1893, and in Great Britain, No. 15,403, datedAugust 12, 1893.

In the application for patent referred to the rolls are shown asconsisting of six die disks held together by means of securing disks.Instead of these rolls it is now proposed to use rolls which can beconstructed more simply. According to the present invention each roll isconstructed by placing a tire like ring, the periphery of which hasgrooves or cavities to correspond with the chain links to be formed orwith any other impressions to be made respectively with the section ofthe smooth bar to be rolled, on a core disk of the same width, andfastening the two securely together.

A roll constructed in the manner just de-v scribed, in comparison with aroll composed of a single disk or of several disks secured together, hasthe advantage that the renewal and substitution of worn rolls isconsiderably cheaper, as the core disk can always be used again. Thisroll is illustrated in the accompanying drawings, in which a Figure 1represents a vertical section through the roll. Fig. 2 shows a side Viewof thecore disk-with the tire disk in position. Fig. 3 is a verticalsection on an enlarged scale through four such rolls where they meettogether.

t 1 is the ring disk and 2 the core disk on which the roll disk issimply pushed from the.

side. The rotation of the roll disk on the core is prevented by means oftwo or more keys 3 Fig. 2, which are driven partly in a groove in theroll and partly in a groove in the core. Aclamping or securing disk 4Fig. 1 is placed on each side of the body so formed and these disks arethen firmly connected to the roll disk by bolts 5, which pass throughholes in the disks and in the roll disk. The clamping disks and the coreeach have a central hole.

The shaft 6 Fig. 1 of the roll is passed through these holes until oneof the clamping disks, in Fig. 1 the left, comes in contact with a disk7 forming with the shaft one piece or fixed to the same so as to form aflange thereon. Another flange disk 8, similar to the disk 7, is thenpushed on the shaft from the opposite end and fixed to the shaft by aWedge or other means for preventing its turning and the parts 2, 4, 7and 8 are then finally connected by bolts 9, which pass through holes inthe said parts. The holes in the core disk 2 and the clamping disks 4for the bolts 9 are made oval Fig. 2, so thaton loosening the bolts 9the parts 1, 2, 4, 5-can be revolved to a certain extent on the shaftand in this manner the grooves or cavities 10 Fig. 3 can be brought intothe correct position relatively to those of the other three rolls. Thishaving been done, by tightening the nuts of the bolts 9 a frictionalresistance will be produced between the disks 7 and '8 on the one handand the parts 1, 2, 3, 4, 5 forming a hole on the other hand, whichresistance serves the purpose to maintain the parts 1, 2, 3, 4, 5 in theposition given to it with relation to 7 and 8.

The thickness of the roll disk and of the core disk depends on the sizeof chain to be formed. In order, however, to enable the same rollingmill to be used-for chains of various sizes the total thickness of theroll or core disks and the clamping disks must always remain the same.When therefore, the ring is made thinner the clamping disks must be madethicker and with a thicker roll disk the clamping disks are madecorrespondingly thinner. In the case of very thick roll disks theclamping disks 4 are done away with and the outer disks 7 and 8 are usedas clamping disks.

In this manner the shaft and the outer 1o 1 disks 7 and 8 as Well as thewhole rolling mill can be used for chains of various sizes and shapes.

By providing in combination with parts 1, 2 and i the keys 3 and bolts5, it becomes possible to assemble the operative parts of a roller intheir proper relations to each other previous to mounting the same onthe roller shaft, thereby saving time when it becomes necessary tochange from one pattern or cross'section of the article to be rolled toanother; and further, as all these parts are united into one body, theadjustment of the grooves and cavities on the periphery of a roller withreference to those on the other three rollers can be easily accomplishedthrough the instrumentality of bolts 9, 9 as heretofore described.

Having fully described my invention, what I desire to claim and secureby Letters Patcut is 1. In a roll, in combination with its shaft, acentral portion carrying the operative roll surface and being movablearound its shaft,

a fixed flange and a detachable flange on said shaft and facing oppositesides of said central portion, and bolts passing through said centralportion and said flanges, said central portion provided with elongatedholes for-receiving said bolts, for the purpose of adjusting therelative position of central portion and flanges with reference to eachother and with Feference to the shaft, substantially as set orth.

2. In a roll, in combination with shaft 6 and fixed flange 7, core disk2, roll disk 1, keys 3, clamping disks 4, 4, bolts 5, 5, detachableflange S and bolts 9, 9, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

OTTO KL ATTE.
